Availability and distribution of copper in soils following eight annual applications of CuSO₄ or Cu-enriched swine manure
… regions of Virginia, respectively. A laboratory incubation study was also conducted using the same soils to determine the effects of soil pH on the changes in forms of soil Cu present over a 256-day period following addition of CuSO₄ or Cu-enriched swine manure. Application of 336 kg Cu ha⁻¹ , as …

Availability and distribution of nitrogen and phosphorus from sewage sludge in the plant-soil-water continuum
… and P haâ 1, respectively. A 14-day anaerobic N incubation study indicated that mirreralization varied from approximately nine to four percent of sludge N from the 42 to 210 Mg haâ 1 application rates, respectively. Sludge application increased N uptake (rz = 0.98** to 0.99**) by the 1984 com …

Lignin and carbon transformation in roots of maize and mixed perennial biofuel crops
… as biofuel crops alternative to maize. In this study, fertilized and unfertilized mixed perennial prairie crops were compared with a conventional maize-soybean rotation and to continuous maize cropping systems to assess the potential production of above- and belowground lignin. The quantity and …

Development of Novel Liquid Chromatography-Electrospray Tandem Mass Spectrometry Approaches for the Structural Characterization of Brevetoxins Including in vitro Metabolites
… are produced by “red tide†algae. In this study, brevetoxin-1 and brevetoxin-2 were incubated with rat liver hepatocytes and rat liver microsomes, respectively. After clean-up steps, samples were analyzed by liquid chromatography-electrospray mass spectrometry (LC-ES-MS). Two metabolites …

Soybean nitrogen dynamics: Nitrogen fixation, yield, and residue decomposition
… US N budget estimations.</p> <p>A long-term incubation study was conducted by using aboveground plant litter of soybean along with three other plants (maize, oats, and alfalfa), to investigate the effect of different litter amendments on mineral associated organic matter (MAOM) accumulation …

Effects of Manure Injection on Transport and Transformation of Nutrient and Antibiotics
… to surface application after volatilization, incubation, and rainfall simulation studies. Although these benefits did not translate to higher yields in orchardgrass hay, protein increased when poultry litter was injected, indicating greater N uptake. Injection of dairy manure decreased losses …

Phosphorus Losses in Runoff from Virginia Soils
… were collected and used in a rainfall simulation study. Phosphorus retention among separated clay fractions and whole soils were related to Al bearing minerals such as hydroxy-interlayered vermiculite (HIV), gibbsite, and amorphous Al. Samples dominated by kaolinite retained very little P. …

Nutrient Availability from Poultry Litter Co-Products
… regions, such as the corn-belt. We initiated incubation and field studies on sandy loam soils to test P and potassium (K) availability from poultry litter ash (PLA). Four PLA products, derived from different sources using different combustion techniques, and 2 biochar products were …

Carbon dioxide emissions from selected soils in Zambia : effects of nitrogenous fertilizer and agricultural lime.
… ways of reducing CO2 emissions from soils. This study was conducted to assess the effects of applying agricultural lime and an NPK fertilizer on CO2 emissions from soils and to identify soil properties that have a significant influence on soil organic carbon (SOC) contents and on soil organic …

Soil properties, lime and phosphorus fertiliser management affecting grass production in Ireland
… soils in Ireland. A controlled soil - only incubation study was undertaken across 22 grassland soils to investigate the fate of applied P fertilisers (chemical and organic P) with and without lime applications. A simulated grass silage (3 cut) pot study was then conducted across the same …
